Mobile phones are small electronic devices, based on the telephone (which in fact also used as a signals provider) which allows two or more separate communications links to be made. A mobile phone can make and receive calls on a conventional radio frequency network using the same channels that are used for the reception of other signals. Mobile phones can be used with a regular telephone handset as well as cordless telephones. Mobile phones can also be used to communicate with various portable devices such as digital cameras, mp3 players, laptops and other net-enabled personal computers and handheld networking equipment.
There are three basic models of wireless mobile phones: the CDMA model which is used in Europe and Asia and the GSM model which can work in North America and a variety of European and Asian countries. CDMA mobile phones use a short-code system to allow only specific phone numbers to call. GSM mobile phones connect to a Global System for Mobile Communication (GSM) network and can be used with other networked personal computers and devices which are equipped with the same operating software.

The modern mobile phone has changed drastically since its inception. Initially, the mobile phone was an expensive device mainly used for making long and short distance calls. Nowadays, mobile phones can be used for video conferencing, playing games, downloading applications and Internet content, making and receiving calls, and a host of other functions. Some models of mobiles are capable of linking to the internet via data networks such as GPRS and UMTS. Some mobile phones are also capable of connecting to international base stations which allow for seamless long distance calling.
